Antimicrobial Assay Of Sagebrush Roots, Lauren Rachel (Moody) Mcfadden
Undergraduate Honors Capstone Projects
Plants produce secondary metabolites for various functions, one of which is antibacterial activities. Sagebrush has historically been used by Native Americans for different medicinal purposes, suggesting that it may have secondary metabolites that would have medicinal values, including antimicrobial activities, and can be a natural source for antibiotics. This study aims to carry out the antimicrobial activity of Sagebrush root extract against a handful of bacteria. We tested the antimicrobial activity of root extract of Sagebrush against six bacteria such as Bacillus subtilis, Bacillus cereus, E. coli DHSα (Lab cloning strain), Agrobacterium tumefaciens GV3101 (Lab cloning strain), Pseudomonas …

Scientists who study aquatic ecosystems quickly notice a diversity of pathways that different microbes and organisms can use to metabolize nutrients found in common ponds or pools. Competition for vital resources, such as light and inorganic minerals, allow only certain organisms to grow in certain niches within these ecosystems. Rhodospirillum rubrum is a gram negative, photosynthetic bacteria that competes for light within aquatic ecosystems in order to survive. R. rubrum is believed to specifically absorb light for photosynthesis at wavelengths in the range of infrared light. It was found that R. rubrum indeed can grow in "dark", anaerobic environments by …
